Any regular military unit is considered a leg unit by the personnel in SOCOM, USASOC, and JSOC. "Grunts"/regular infantry, five jump chumps, anyone training to conduct in airborne ops in garrison but never perform them in combat, and all POG 's are defined as Legs. It is as much a mindset as it is a status.

The 82nd Airborne (AKA: Eighty Douche) takes pride on jumping as much as possible, wearing pink berets, blasting Van Halen's song "jump" around post, but NEVER perform airborne or helo ops in combat. This makes them epic posers, puts them in the Leg category, and earned them the title "The airplane gang".

Many service members attend airborne school, thinking being "airborne qualified" will impress others. They then report to a leg unit who has nothing to do with airborne ops and never jump again, making them a "five jump chump" and a leg.

L.E.G.S. - Abbreviation for "Lame Excuse to Get Sex" or in other words, "Lame Excuse to Get Laid". A lame reason used by a girl or guy to ask the opposite sex partner to come over in order to get some.
